Aim The aim of the experiment is to test whether changing a certain variable in an electromagnet circuit (either the coils around the core or the current- the flow of electricity around the circuit has any affect on the strength of the electromagnet which is tested by its magnetic strength. Prediction and Hypothesis This prediction is going to be based on two different variables, one is changing the number of coils around the core of the electromagnet and the other is altering the current (flow of electricity) around the circuit on the power pack. The prediction is that when the number of coils is altered whether it is more or less; the strength of the electromagnet will be changed whether it is stronger or weaker. When a wire is coiled and wrapped around a core (iron nail) it makes the electromagnet stronger than it would be just having a straight wire. The coils...
